Troika_Falling Light from Troika on Vimeo.London-based art collective Troika, whose art and design works have garnered them plenty of interest in recent years, have created an installation that immerses its audience in a shower of light drops.The installation, Falling Light, consists of 50 suspended mechanical devices, each incorporating a custom cut Swarovski crystal optical lens. A computer-programmed motor and a white LED light rise and fall, moving closer and further away from the crystal in syncopation. Using the crystal’s most basic optical properties, the LED’s movement creates perfect rainbow halos as the droplets expand. In line with Troika’s constant agenda that “science does not destroy, but rather discovers poetry in the patterns of nature”, Falling Light uses the natural diffraction of light through crystal, combined with the drone of the mechanical arms, to give a living, breathing feeling to the steady drops of light.The commission was originally for Design Miami, a yearly fair that invites collectors and enthusiasts to interact with pioneering modernist artists and designers. They have been working with Swarovski Crystal Palace since 2006, but Falling Light is seemingly the first artwork that has made use of the diffracting and manipulative qualities of cut crystal.Originally commissioned in December 2010, Falling Light is now being exhibited by Input/Output Gallery in Hong Kong until July 25th, 2011.
